    I would think he is talking about something like a small subpanel w/ breakers to outlets, fed by a 50A RV outlet off the main panel

    Here's what I made. It's 'portable' in the sense that it can be removed from the wall and stored, then re-attached on the wall. See the 2 wing nuts on the top (but I think there is a little angle bracket on the bottom, too).


    I feed the box by suitably large (14awg - 12awg) power cords. There are 4 circuits, mostly 15amp but one 20Amp (based on the in-wall wire and circuit-breaker). I split each circuit into 3 or 4 sub-circuits. I plan my display so each (sub)circuit carries about 5 Amps max.

    (Ignore the red-and-white striped PVC antenna cover.)

    Each circuit enters a 3-gang electrical box, and a pigtail that allows another 2-gang box to be connected. The satellite 2-gang box holds 2 GFCIs. The main box contains a 40Amp crydom SSR (that gets powered up by the computer when it turns on), and switches to control operation. One switch (“Run”/”Off”) enables the circuit so it can come by computer-control, and another one to force it on (override on called “On!”/”Ext”)) for testing independent of computer. On this switch “Ext” means external control.

    The gray box in middle lower also has a master “Ext”/”Off”/”Int” 3-position switch, When ‘Off”, nothing has any power. When “Ext” the the external computer controls whether to turn everything on. With “Int” 9v battery inside the gray box is used to turn on the setup without computer, again for testing.

    Each circuit includes a green 10mm LED which light up when the circuit is ‘armed’, awaiting external (or internal) signal to turn on.

    In this photo, circuit #4 is not completed, but it has since been completed.) The timer was only temporarily in use until is was done.

    I added a copy of my power layout plan. This hangs near the power panel so I can know what display elements to look at if I do have ground fault issues.

    Lastly, I installed a night-light in each GFCI, with a green filter, and switched on. When the receptacle has power, the nightlight turns on green. When off, the nightlights go out. This way I call tell at a glance (from my internal garage door in the kitchen) if any and which sub-circuits may have tripped due to ground fault.

    Is this what you are looking for?

    I think you need a few more indicator lights............

    Here's what I use in the UK, metal IP65 enclosure with a 32A inlet split to 4 13A sockets and two 16A weatherproof sockets, all on individual MCBs. There's space in the bottom of the cabinet for other things to sit (one of my DMX decoders in the picture). It's also got a couple of LEDs to show incoming power and RCD status.

    My brother said it looked like a crap R2D2 and stuck googly eyes on the indicator lamps...!

    It may not have been clear from my explanation, but each GFCI receptacle (pair) is a separate sub-circuit. So I have an indicator on each of the 13 sub-circuits. it makes i much easier to quickly figure out where the leakage is occurring in any Ground Faults happen.

    PS As I recall, those are YOU'RE Crydoms in there... That makes you complicit, at least in principle.
